Bond Impact Crushing Work Index -Procedure and Table of ...

Jun 16, 2015  Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.
